[sane-devel] Possible Sponsorship for Avision Backend Modification

[daniel at pixelgrease.co]

Hi all, 

I tried to download the source, and get editing. I am a competent
programmer (was my fun time job for 3 years) but I've never worked with
C or C++. 

Got lost at trying to build an environment that supported debugging.
Some error about a missing file when I attempted to compile. 

My use case for the scanner is very simple. I just need a simple colour
scan at a set dpi. Don't need any fancy features. (not sure if that
helps or not) 

Is anyone here capable of adding a device to the Avision driver? I can
supply a ssh into a device connected to the scanner. 

Any idea of how much this would cost? 

Below is the initial call for help I sent out last week regarding the
device 

Thanks!

Hello all,

Been trying to get a scanner with an avision scanner to work. The
scanner name is "WorldCard Pro (Win/Mac)"
http://www.penpowerinc.com/product.asp?sn=407

It's not listed as supported, but thought I might get lucky. My thinking
was that if it's supported by Mac, it should work with linux. Tried
specifying all sorts of values in /etc/sane.d/avision.conf but nothing
seemed to work. 

Is there a way to add support to the existing avision backend? 

Thanks for  your help! 

Daniel
